Stone Identity & Quality
This is a 3.41 ct Facet Grade Ceylon Natural Blue Sapphire Rough, measuring 8.9 × 7.2 × 4.9 mm. The stone is sourced from Rakwana village around mining in Sri Lanka and remains in its natural unheated condition. This material is locally known as ottu-type sapphire rough, which can be studied for cutting, polishing, and possible heat treatment depending on the buyer’s purpose and the cutter’s assessment.
Color & Visual Characteristics
The stone displays a natural blue sapphire body color with strong surface areas and visible blue zones. As with many unheated sapphire roughs, the final color after cutting or treatment depends on orientation, depth, internal structure, and professional planning. The current rough form gives the buyer a natural view of the stone before any treatment or cutting decision is made.
Internal & External Features
This sapphire rough shows visible natural surface features, rough texture, and internal characteristics that should be studied carefully before cutting. These features are normal in uncut sapphire material and must be considered when planning the final shape, yield, and polish. The stone has usable depth and a solid rough body, making it suitable for careful examination by gem cutters and rough sapphire buyers.
Cutting & Treatment Potential
As facet grade rough, this sapphire has potential for custom cutting after proper orientation study. The stone may also be considered for heat treatment to improve or strengthen the blue color, as this type of ottu material can sometimes respond well. However, no final treatment result is guaranteed, and any heating should be done professionally after evaluating the stone’s structure, inclusions, and risk factors. Possible cutting directions may include a custom oval, cushion, fancy shape, or another design based on the cutter’s judgment.
